Complex-shaped surface represents one of the challenges in ultrasonic testing of metal castings. This conditions the growing interest in development and application of the automated testing system based on a six degrees of freedom (DOF) robotic manipulators. This is due to their ability to provide ultrasonic scanning of the curved specimens with high speed. Higher reliability of the results can be...
After the Fukushima accident many people have lost the confidence in the save operation of nuclear power plants (NPP). Nevertheless, most of the countries with nuclear power plants under operation or construction, confirmed their plans to develop their nuclear capacity in the future. But without any doubt peaceful use of nuclear energy is a system which needs to be improved. There are three main elements...
Positron annihilation spectroscopy techniques are sensitive laboratory methods of in-depth study of the material structure and processes occurring in it. The digital spectrometric system described in this paper is designed to study the defect structure of materials by positron annihilation spectroscopy techniques. This system combines the methods of positron annihilation lifetime spectroscopy and...
The Government of the Russian Federation has intention to develop nuclear energy and involve in the fuel cycle additional amount of fissile materials. In theory it could lead to increasing activities of terrorist's groups by using nuclear materials as an object for blackmailing. The governmental system of nuclear material control and accounting was dedicated to prevent alike scenarios. Unfortunately,...
